What is better? 2 decent subs -> say 300 watt OR 1 great sub -> say 600 watt?

Since my stereo was so graciously "relocated" by some SOB, I need to get another one and I want to do it right. I listen to everything from DMX - > Korn -> Linkin Park -> UPO -> just about most types of music. I want something that will sound good no matter what I am listening too. Whatever it is it will be in a custom made sub box made to fit the trunk contuor.

i'd say get 1, something like an alpine type r or a infinity dvq.
Plus, one sub mean less weight........GO FASTER

Depends on whether you want tight clean bass or loud boomy bass.
Two are always better than one when it comes to loudness but you need clean power to drive them. Not all amps are equal even if they are rated at the same wattage output.
A 3 dB increase in sound level is a doubling of sound intensity and it takes twice as much power.
If not 1000 watts for two subs than stay with one sub and give it some good clean power.....like around 600 watts.

i would go with two infinity perfect 12'* that is what i have and they sound very clean but still have an extreme amount of bass a little pricey though

If you want a good sounding clean loud sub... I would suggest a set of 10" Kicker CVR'*. They hit everything from and Bass Guitar Solo to a Gangsta Rap Beat. I have a set of the Kicker Comps and they sound awesome when I am listening to any type of music.

Hey gordy, look at some Fosgate Punch HX2 (500w) or even the POWER HX2 (1000w) They slam, and are very tight. Work well for rock IMHO, and have some in my friends 91 Firebird.

the punch hx2'* are 1000watts (i've had them)
and the powers are 2000

i love the powers they are tight....but most people dont know cuz they buy from a place such as best buy that doesnt carry the higher end of RF

Crutchfield has the best prices on that higher end RF stuff, and yes it is amazing. Best buy is crap i used to work there, and boy i have stories to tell...
